Ink viscosity is too low.
Measure ink viscosity, if viscosity is less than 1.1cP, replace the ink.
Verify the board is the set to the correct Fluidic Generation.
Lift Makeup pickup tube out of the tank. In Fluidic Screen, Run to 40PSI and watch to see if there is
flow. If the makeup flows, the Makeup Add valve is clogged open and should be cleaned or replaced.
If not using BestCode provided fluids, inspect ink for foaming. This can cause ink to become thin over
time.
Ink viscosity is too high.
Measure ink viscosity, if viscosity is more than 10cP, replace the ink.
Verify the board is the set to the correct Fluidic Generation.
Lift Makeup pickup tube out of the tank. In Fluidic Screen, Run to 40PSI and enable the Makeup Add
valve. Watch to see if there is flow. If the makeup does not flow, the Makeup Add valve is clogged shut
and should be cleaned or replaced.
If not using BestCode provided fluids, inspect ink for foaming. Foam causes ink to seem thick by
increasing the fall time of the ball in the viscometer. Look for air in the Viscometer glass tube.
Viscosity %6.2f out of valid range
Check the Ink Viscosity. If it is more than 10cP or less than 1.5cP replace the ink.
Let the system run until viscosity has returned to normal.
Viscometer rise not detected.
Clean or replace the viscometer.
If not using BestCode provided fluids, inspect ink for foaming. Foam may prevent viscometer from
operating correctly.
Viscometer fall not detected.
Clean or replace the viscometer.
If not using BestCode provided fluids, inspect ink for foaming. Foam may prevent viscometer from
operating correctly.
SmartFill command label not valid.
Try scanning new SmartFill command label
Check coax cable connections from the SmartFill cup.
